Oil prices swung sharply on November 3, 2026, as traders weighed renewed military risk against signs that US–Iran diplomacy was continuing. The Qeshm Island strikes helped lift Brent and WTI early in the day, but the later decline had multiple possible influences; the available reporting does not establish that an unconfirmed draft memorandum caused it.
From Monday’s selloff to Tuesday’s reversal
On Monday, Brent settled at $104.77 a barrel, down $8.66, or 7.63%. WTI settled at $96.46, down 7.4%. Reports of Iran–Qatar talks had raised hopes that the conflict might ease and that supply disruption risks could recede.

The initial move on Tuesday went the other way. After reports of US strikes on Qeshm Island, Brent reached $106.61 and WTI $98.06 in early trading. An Iranian official’s warning that a deal remained distant added to concerns about escalation and possible energy-supply disruption.

Prices later fell. Reuters reported that at 1350 GMT Brent was down 3.3% to $101.32 and WTI was down 2.2% to $94.30, after both had traded above $107 and $98, respectively. The report linked the slump to President Donald Trump’s announcement that the United States would end billions of dollars in annual military support to Israel. That timing means the late-session drop should not be attributed solely to the draft-deal headlines.

Why strikes and diplomacy could move prices in opposite directions
Oil traders were responding to two competing possibilities. The strikes raised concern that hostilities could escalate and threaten supply; signs of negotiation raised the prospect that those risks might ease. Both can affect prices before anything changes in the physical flow of oil.
US officials described the Qeshm operation as limited and defensive, saying it targeted surface-to-air missiles used against American assets. That explanation characterized the strikes as distinct from a return to major combat operations, even as the news prompted fresh market concern.

Diplomacy was also still in progress, according to Qatar. Its foreign ministry spokesperson said Washington and Tehran were reviewing proposals put forward by mediators and remained engaged in the negotiation process. That is evidence of ongoing mediation, not confirmation of an agreement.

A separate report said Washington had backed a draft memorandum presented by Qatari mediators. But the report relied on sources close to the mediation team, and the provided coverage said no official agreement had been announced. Treat the memorandum claim as unconfirmed, rather than as a settled explanation for the market move.

What the price action says about the outlook
The day’s swings show how quickly oil can respond to changing expectations about conflict and negotiations. They do not, by themselves, prove that supply flows changed or that a peace deal was close. Qatar’s public account confirmed proposal reviews; it did not establish that the parties had resolved their differences.

The risks therefore remained two-sided: credible progress toward an agreement could reduce some of the geopolitical risk premium, while stalled talks or renewed escalation could restore upward pressure. Goldman Sachs’s higher Brent forecasts and warnings about supply risks underscore why diplomatic optimism did not eliminate the possibility of further price increases.

The key distinction is between a reported framework and an implemented agreement. Until terms are confirmed and there is evidence of a lasting change in supply risk, headlines can move prices sharply without settling the market’s underlying uncertainty.
